ʻO Diethyltoluenediamine (DETDA) CAS 68479-98-1
ʻO Diethyl-toluene-diamine (DETDA), helu CAS 68479-98-1 he mea hoʻōla wai diamine ʻala, kahi like me Ethacure 100 a me DETDA 80, no ka polyurea a me ka polyurethane (PU).
Ma ke ʻano he mea hoʻolōʻihi kaulahao kūpono no nā noi polyurethane, ʻo DETDA kahi hopena kūpono me kona kumukūʻai haʻahaʻa a me nā waiwai maikaʻi loa, ʻoi aku hoʻi no RIM (reaction injection molding) a me SPUA (Spray Polyurea Elastomer). Hiki i ka DETDA ke hoʻōla i ka polyurethane/epoxy i ka manawa pōkole loa, ʻaʻohe tack i kekona a sila pono i ka ʻili e pale i nā papahele, nā facades, nā kaupaku a me nā alahaka. ʻO ka mea maikaʻi loa, uhi a sila ka polyurea ʻano DETDA i nā ʻili kū pololei i loko o kekahi mau kekona me ka ʻole o ka sagging.
ʻO DETDA ka mea hoʻolōʻihi kaulahao maʻamau i ka ʻoihana polyurethane, he haʻahaʻa kona mānoanoa, hiki ke lawelawe maʻalahi a ʻoi aku ka launa pū me ke kaiapuni. Ma ke ʻano he ʻano wai, hiki ke hana ʻia ʻo DETDA ma ka mahana o ka lumi a hoʻōla maikaʻi ʻia. Eia kekahi, he kiʻekiʻe ke kūpaʻa o nā elastomers ʻano DETDA e like me nā mea ʻano MOCA. I kēia manawa, ʻoi aku ka liʻiliʻi o ka ʻawaʻawa a me ka lepo i loko o ka hale hana hana i ka hoʻohālikelike ʻana me MOCA.
E like me kona hoʻohana ʻana i ka polyurethane a me ka polyurea ma ke ʻano he mau mea hoʻōla, hoʻohana ʻia ʻo DETDA ma ke ʻano he mea paʻakikī a me ka crosslinker no nā resins epoxy. Hoʻopili kāna mau hui amine ʻelua me nā hui epoxy ʻehā, a hana pū i kahi kikowaena crosslinking wela kiʻekiʻe me bisphenol A. Ma ka hoʻoponopono ʻana i ka dosage, hiki i ka DETDA ke hāʻawi i ka pane wikiwiki a me ka laulā cross-linking i ka wā e koi ʻia ai.
Ke hoʻohālikelike ʻia me DMTDA, DimethylthioToluene Diamie, ʻaʻohe ʻala sulfur ʻoluʻolu ʻole a ʻoi aku ka paʻakikī o nā huahana hoʻōla i hoʻopau ʻia me nā waiwai kino maikaʻi aʻe.
Hoʻohana nui ʻia ʻo DETDA ma ke ʻano he mea hoʻōla no ka ʻōnaehana pīpī polyurethane/polyuria no ka pale lōʻihi o nā ʻili āpau. Me kona waiwai hoʻōla wikiwiki, hoʻohana nui ʻia ʻo DETDA i nā mea kūkulu hale a me nā mea hana hale. He hopena kūpono ia e koi ana no ka uhi/sila wikiwiki, kūpono a mau loa.
No ka poʻe e hana ana i ka pīpī ʻana i nā uhi polyurea, polyurethanes, composites a me epoxy resins, e paʻakikī iā ʻoe ke loaʻa nā pani DETDA e kūpono i kāu mau pono hana. ʻO kona wikiwiki hoʻōla kū hoʻokahi e hoʻolilo ia i mea hoʻokahi o ke ʻano.
Eia kekahi, hoʻohana ʻia ʻo DETDA ma ke ʻano he mea hoʻōla/crosslinker o ka polyurethane a me ka epoxy resin, antioxidant o ka epoxy resin, ka ʻaila ʻoihana a me nā lubricants. Eia kekahi, hoʻopili ʻia ʻo Diethyl-toluene-diamine ma ke ʻano he waena i ka synthesis organik.
Hoʻopili ʻana: 20kg, 200kg/pahu hao. a i ʻole IBC TANK.
Ka mālama ʻana a me ka halihali ʻana: E pale i ka hoʻopili ʻana me ka wai. E mālama mai ka lā.
